Before posting any report, and if you're only seeing issue on an individual WU (it can fail up to 6 times in a row before moving to another one), please check if it has already been reported as a bad WU in this forum : viewforum.php?f=19 ... if you're having issue with multiple WUs (different Project/Run/Clone/Gen numbers), please do what is described below.

I've recently seen many reports of errors on NV GPU, so I decided to create this thread. It is intended to centralize reports, and to split them from discussions around the issue. The goal is to help find a pattern that could trigger the issue. To make your report, please quote my post, and remove any line in each section that doesn't apply to your case.

Failing projects (please add a list of exact project numbers if you have them)

[*]Failing drivers (enter here the version number of the driver you use)180.60 - No successful units completed181.20 - Has started to return units successfully after acting like the 180.60 drivers for some time

[*]Comments (add below any detail you might find useful to the report)This card ran for several weeks without EUEing on its own in a WinXP 64bit machine with 180.60 drivers on Intel Core2 hardware.

After being transplanted into a new machine it near constantly EUEed with the 180.60 drivers and after trying the 181.20 drivers with the same results I turned off the client and left it for a day. The following day I started the client up again which resulted in the strange units that progressively failed and then suddenly completed. Since then I've had this occur again. AMD 790FX 64x2 hardware this time.

This machine also has three other identical cards folding, and this card is GPU0. This is the only card with issues.

Failing OS* Windows Vista 64 bitNote: OS is not actually failing. System is extremely stable, but this is the OS I'm using. UAC is ON.

Failing drivers (enter here the version number of the driver you use)nVidia 185.20 PhysX v8.11.15

Comments (add below any detail you might find useful to the report)This system has folded these units absolutely flawlessly since Christmas. I've done two driver changes since that time and each has performed with a 100% success rate up until those 5 WU's above failed which filled up the Queue.dat and shut the client down. I attempted to restart and the Client again failed. I then shutdown the client to investigate. At rthat point I was stuck with the question "Should I Uninstall and Clean the Folders and Files and Reinstall and attempt to get work done overnight, or wait?" I decided the best course of action was to Uninstall, clean the reg of the FAH folders which effectively got rid of the Queue.dat and all the associated files, and get the client up and running again by reinstalling a clean install. I felt like ti was better for the project to get the work done and have to recycle those WU's which I had leanred were recycled fairly quickly, then to let my system idle overnight. I felt like I had to choose between the worst of two evils. I hope I chose correctly.

The Client since that time has been folding flawlessly with not a single WU lost. I don't know if this was a client issue, or a Bad WU, but it seems to be related to those 5763's. I had 5 out of 5 fail 100%. I have since folded 9 out of 9 WU's total with a 100% success rate, and it's currently 91% of the way through a 5763 and looks like it's gonna finish.

Edited to add: The 5763 noted in the above paragrpah did complete since clicking send on this post. I do NOT understand this now.

Since the wipe and reinstall it does seem like the client is a little quicker, but I will have to watch it a couple more days before I can say that for sure.

This machine has some of the best hardware that money can buy. It has an i7 965 CPU on a Rampage II Extreme Motherboard. RAM is Corsair Dominator 1600 C8. The GPU has been tested stable with numerous programs including Furmark, LightsMark, 3DMark apps, and has literally been pounded with Furmark for hours before I started folding with it back just before Christmas. Up until that incident above it's never given me a hint that anything was ammiss, or unstable.

System: 2 x ASUS 9600gso/TOP @ 600/900/1700, msi k9a2 platinum, ea380 psu, ForceWare 177.84, 6.20r1, 1.19, XP 32 SP3, X2-3800, everything as it came out of the box. Nothing has changed on my end for many months, This machine originally got few errors, then 20% errors with shutting down, now back to this.

3 UNSTABLE_MACHINE out of 405 WU's in the current logs (0.7%). All on the first card. No failures on second card. No display or terminator on second card.

Thank you for posting this information. We are looking into it. If you could post specific Project, Run, Clone, Gen/Frame info, that would be particularly useful, since we would then go to look at that particular WU and run it in house and give it a strong scrubbing.

My experiance is that when I have repeatedly failing folding issues a reboot often fixes the problem. This seems to be true for both Nvidia and ATI. It doesn't fix all problems, just the vast majority of them. the GPU clients just plain don't seem to be stable 24x7 but rather after a few weeks of continious folding, they inevitablly start EUE'ing or unstable machining and then after a reboot they start working again.

[*]Failing drivers (enter here the version number of the driver you use)Lenovo ThinkPad driver 7.15.11.7597

[*]Comments (add below any detail you might find useful to the report)Tried GPU on my ThinkPad T61p. It worked much of the time but would sometimes fail with Unstable error and NAN error. I figured the GPU cooling in the laptop wasn't good enough for sustained folding and gave up and now just run FAH smp on the ThinkPad.

In addition, temps are ~38degC at load (my attic is cold in the winter) and stock clocks on the problem card (lowering the clocks doesn't help)
